The short answer
- Around September 20, 2026, about 12 days after launch, Amazon began blocking Muse from shopping on Amazon.com.
- Amazon says Meta didn't tell it Muse would access the store, that Muse doesn't identify itself, and that it appears to capture customer credentials. Meta denies Muse can see passwords or payment methods.
- Other retailers are taking the opposite approach. Shopify partnered with Meta, and Walmart and Best Buy were named as Muse partners at Meta Connect.
- Workaround: ask Muse to compare prices including Amazon, then buy on Amazon yourself, or let Muse buy from a retailer that allows it.
If you've asked Muse to buy something on Amazon and hit a wall, here's why: Amazon is blocking Meta's agent on purpose.
What happened
Around September 20, 2026, roughly 12 days after Muse launched, Amazon began blocking Muse from shopping on Amazon.com. Reports differ by a day on the exact date. Muse users who try now see a pop-up saying continued access by an unauthorized AI agent violates Amazon's Conditions of Use.
Amazon's reasons
According to reporting on the dispute, Amazon says:
- Meta never told Amazon that Muse would be accessing its store.
- Muse doesn't identify itself as an AI agent while browsing.
- Muse appears to capture and store customer credentials, which Amazon calls a privacy and security risk.
Amazon says it asked Meta to remove Amazon from Muse's shopping features, and Meta declined.
Meta's response
Meta says Muse has no visibility into people's passwords or payment methods. Credentials sit in secure storage that the agent can use without directly seeing. Purchases use one-time card numbers through Link by Stripe.
The bigger picture
This is less about one app and more about who controls shopping when AI does the clicking:
- Amazon earns a large share of its revenue from ads shown to shoppers on its site, around $68 billion a year according to Forbes. An agent that skips straight to checkout doesn't see those ads.
- Amazon has restricted other outside shopping agents before, including Perplexity's Comet. A court ruling in August weakened some of Amazon's legal arguments in that case.
- Other retailers are going the other way. Shopify partnered with Meta to support Muse, including Shop Pay. Meta named Walmart, Best Buy, Sephora, Instacart and Expedia among partners at its Connect event (some connectors are still listed as "coming soon").
- Amazon and Meta are still business partners elsewhere. Meta signed a deal in April 2026 to use Amazon's Graviton chips.
What it means for you
- Muse can't reliably shop Amazon for you, and this may not change soon.
- Comparison shopping still works, with a manual step: check Amazon yourself and ask Muse to compare against other stores.
- Muse is likely to steer purchases toward partner retailers. That's fine, but keep checking total prices.
